The present invention relates to a knife ring joint, the purpose whereof is to reduce mechanical friction and to increase weighing accuracy in a scale which is used in the casting of molten material. The knife ring is designed to be pressed in a ring-like fashion against a cylinder surface serving as the countersurface, and any motion in the direction of the lengthwise axis of the cylinder surface is prevented by of a flexible element.
